Claude Fable 5 / Mythos 5 frontier LLM — hosted frontier model

Companies committing: anthropic.

Opportunity: Closed-frontier still owns the leading edge (per b141eb8d), but with rapidly mounting trust friction — pricing up (Forbes), data-collection-by-default (Mashable), capability throttling (Fortune), then walkback (Verge). The product is the model + the policy, and the policy is what's gating adoption.

Best-positioned closed frontier model right now (AWS distribution + IBM coverage), but burning enterprise goodwill faster than at any prior release. The next 60 days are about whether the safety-vs-utility recalibration sticks. Forward-deployed/inference roles at OpenAI/Anthropic/Cursor confirm this is the surface enterprises actually buy.
